Hondaman, thanks for all your info! It's really good to document these things, especially if someone is trying to rebuild/restore one.
The air forks that you suggest for improvement sounds interesting: is there a reference as to how or where to do this? I also notice in your list of performance improvements, that you didn't mention anything about upgrading the ignition points system. 
Well, I hate to sound like an advertisement...
But, the only Electronic Ignition that these 350f can handle easily is the one I make. The alternators on these babes make so little power (85 watts) that a Dyna S can take them to their knees in battery volts. When these bikes were new, they were reknown for, as Cycle magazine once put it, to be "running as soon as you touched the starter button." Today, somewhat less so with the ethanol problem, but I hear that most of that ease reappears when fitted with my boxes. I already bult one for mine, and the bike isn't even close to running yet...
Maybe I could find some local Shriners.... (I am SO jealous!)
